Description

TECHNICAL FIELD

[0001] The utility model relates to the field of calcination kiln, especially to a calcination kiln discharging transition cooling mechanism. BACKGROUND

[0002] The calcination kiln is an important high-temperature processing equipment in industry, which is widely used in ceramic, refractory material, metallurgy and other industries. Its working principle is that the material to be calcined is sent into the kiln through the feeding device, then the heating system is started, and the temperature is raised to the required range for calcination according to the set temperature rising curve. During this period, the temperature control system monitors and controls the temperature in real time to ensure stability, so that the material can fully undergo physical and chemical changes at high temperature. After calcination is completed, the material is taken out by the discharging device after cooling. The parameters of each link need to be strictly controlled to ensure the calcination quality of the material.

[0003] During the cooling stage of the calcination kiln, the choice of cooling method has a crucial influence on the efficiency and product quality of the entire calcination process. Cooling is mainly achieved through natural cooling and circulating water cooling, which have their own characteristics. Circulating water cooling includes cooling water pipeline, water pump, water tank, etc. The cooling water pipeline surrounds or penetrates the cooling parts or the material. The water pump drives the cooling water in the water tank to circulate in the pipeline. The high-temperature material heats the cooling water, and the heated water returns to the water tank, and is then pumped to participate in the next cycle after heat exchange or natural cooling. This method can quickly remove heat and shorten the cooling time, which is of great significance to improve production efficiency and large-scale continuous production. It can also accurately control the cooling process by adjusting the cooling water flow, temperature, etc. to meet the requirements of different materials for cooling rate and final temperature.

The high-temperature gas carries a considerable amount of heat, which cannot be effectively collected and utilized.

[0029] With reference to Figure 3 , Figure 4 and Figure 5 , the other end of the water outlet pipe 12 is fixedly connected with a water adding tank 5, the water adding tank 5 is used for storing the water condensed by the condenser 9, the water adding tank 5 is fixedly connected to the top of the storage box 4, the outside of the water adding tank 5 is fixedly connected with a water adding pipe 21, the water adding pipe 21 is used for conveying water flow into the inside of the storage box 4, so as to perform water cooling operation, the outside of the water adding pipe 21 is fixedly connected to the inside of the mounting plate 20, the bottom end of the water adding pipe 21 is fixedly connected to the inside of the storage box 4, the inside of the storage box 4 is fixedly connected with a refrigerator 23, under the action of the refrigerator 23, the water temperature in the storage box 4 is reduced, so as to prepare for subsequent cooling operation, the top of the water adding tank 5 is provided with a water adding opening 24, the water adding opening 24 is used for manually adding water into the inside of the water adding tank 5.

[0030] Working principle: when the roasting process is over, and the material needs to be cooled, the entire cooling system starts to work. First, the refrigerator 23 is started, under the action of the refrigerator 23, the water temperature in the storage tank 4 is reduced, preparing for the subsequent cooling operation, then the water pump 6 is started, the cooled water in the storage tank 4 is pumped out and transported through the water pipe 7. The water pipe 7 transports the cold water to the spray head 8, when the cold water reaches the spray head 8, the spray head 8 will evenly spray the cold water on the outer wall of the conveying channel 2, cooling the roasting material being transported, quickly taking away the heat of the material. At the same time, the sprayed water is recycled through the return pipe 15, and the pressure relief valve 10 on the return pipe 15 plays an important role in this process. Because a certain pressure may be generated during the cooling process, the pressure relief valve 10 can relieve the pressure of the heat-exchanged hot water. When the pressure relief valve 10 relieves the pressure, the high-temperature gas generated is introduced into the inside of the condenser 9 through the air inlet pipe 11. At this time, the cold water is introduced into the inside of the condenser 9 through the cold water inlet pipe 13 outside the water pipe 7, and the heat of the high-temperature gas is absorbed by the cold water. After heat exchange, the high-temperature gas is condensed. The condensed water is introduced into the inside of the water tank 5 through the water outlet pipe 12, and the heat-exchanged hot water is discharged into the inside of the storage tank 4 through the hot water outlet pipe 14. In this way, not only is the gas generated by pressure relief effectively recycled, realizing the recycling of resources, but also the heat is ingeniously utilized, improving the practicability and energy utilization efficiency of the entire device.

[0031] Secondly, when the water flow in the storage tank 4 is reduced due to use, the buoyancy of the buoy ball 17 decreases, and it moves downward under the action of gravity. The movement of the buoy ball 17 drives the connecting rod 22 and the limiting plate 19 connected thereto to move downward. The limiting plate 19 is provided with a specific through hole, and in the process of moving downward, the through hole will correspond to the hole in the water inlet pipe 21. At this time, the condensed water in the water tank 5 can be smoothly transported to the inside of the storage tank 4 through the water inlet pipe 21, realizing the water filling operation. Conversely, when the water level in the storage tank 4 rises due to water filling, the buoyancy of the buoy ball 17 gradually increases, and it begins to float on the water surface. The floating of the buoy ball 17 drives the connecting rod 22 and the limiting plate 19 to rise. When the limiting plate 19 rises to a certain position, it will block the water inlet pipe 21, thereby stopping the water filling operation. In this way, this automatic water filling mechanism can automatically control the water filling process according to the water level change in the storage tank 4, without manual intervention, greatly improving the convenience and automation degree of the device.
